Aoi, who was engaged to Hiroshi, an employee at her father's factory, was molested and defiled by Horio on a train. Later, she was raped by Horio at the factory, even grinding herself against him in front of her fiancé Hiroshi. During breaks at the factory, Aoi became a plaything for the workers. The acts escalated further, with Aoi exposing her lewd behavior in front of many people on the train and sinking deeper into depravity!
